The dielectric properties of bulk single crystal SrTiO 3 (STO) are studied in the temperature
range 30–300 K, under dc field 0–10 kV/cm at 1.0 kHz and in the frequency range 0.3–2.0 …

Barium strontium titanate thin film varactors have been widely investigated for the purpose of
creating tunable front-ends for RF and microwave systems. There is an abundance of …

Due to stability and lack of toxicity metallic tantalum (Ta), its pentavalent oxide (Ta2O5) and
tantalate complex oxides become commercially attractive in a number of technologies …

The motivation behind the work described in this thesis is to study the coupling between a
